Class BlockCipherParameters

public class BlockCipherParameters extends AlgorithmParametersSpi

An implementation of algorithm parameters for the GNU Crypto block ciphers. This encompasses the cipher's block size, its key size, and an optional initialization vector (IV).

Field Detail

cipherSpec

protected BlockCipherParameterSpec cipherSpec

The underlying block cipher specification.

Method Detail

engineGetEncoded

protected byte[] engineGetEncoded()

Return these parameters encoded in ASN.1 (DER).

For GNU Crypto block ciphers we will define these parameters as

BlockCipherParameters ::= SEQUENCE {
   blockSize            INTEGER,
   keySize              INTEGER,
   initializationVector OCTET STRING OPTIONAL }

Returns: The parameters, encoded an an ASN.1 DER sequence.

Throws: java.io.IOException If encoding these parameters fails.
